Variant Array Problem

[DAckermann]

Hello,

I am having a problem with variant array conversion.

A VI gets a 1D array of generic data type as variant. This VI generates a 2D array of this and passes this to a third VI which has to write that data into a 2D array by the "Value" Property as variant of a control element.

I somehow cannot convert the 1D array of variant into a 2D array of data.

I can demonstrate it with a simplified VI that is demonstarting the problem.

I hope someone can help me out.

You cannot directly convert an array of variants (of 1D arrays) to a 2D array. "Variant to data" accepts a variant, not an array of variants.

What are you actually trying to do with all this?

[jcarmody]

You have a 1D array of variants.  This'll get your 2D array back.

Or, move the To Variant node to the inside loop.

...or, to the outside of both loops.

Sorry, my example doesn't reall describe what I need to do.

I created a new example. The VI architecture is fixed and the data generated by Sub 1 is generic. It can be numeric, string, bool..

I nned to be abl eto write the 2d array by reference to the control and hope somehow to do it without another conversion step.

Thanks

Your first problem is that you want to put a string into a numeric indicator.  That's not gonna work.

A smaller problem is the way you're putting the array of variants into another variant in sub 2.  This works if you change the False constant to True in sub 1:

sorry for the confusion with the boolean constant. It was meant to write the numeric values.

I found a workable solution for me. It works, when scalar valuse are converted to variant and then arrays of variant are built.

How are you going to handle this?
